` 9- claims. (C1. 19g-220) This invention relates to improvements incon-` necting means for 4the troughs 'of a shalrer com veyor trough line.

Theprincipal objects of my invention are to provide an improved and simplified form of con-- necting means for connecting the troughsofa shaker conveyor trough. line together, which is `of a quickly detachable form` and does away with the usual connecting bolts heretofore used for this purpose.

This and other objects of `my invention will appear from time to time as the following specilication proceeds and with reference `to the accompanying drawings wherein:

Figure 1 is a fragmentary plan view of adjacent ends of the troughs of a shaker conveyor trough line. with 'certain :parts of the troughs broken away and shown in section: Y

Figure 2 is an enlarged fragmentary view in side elevation of the troughs shown in Figure l;

Figure 3 is an enlarged fragmentary transverse sectional view taken substantially alongline, 3443 oFigurel; i Tp,

` Figure 4 is a fragmentary sectional view taken substantially along line 4--4 of Figure 3: and` Figure 5 is a sectional View taken substantially along line 5 5 of Figure 3.

In the embodiment of` my invention illustrated in the drawings two shaker conveyor troughs lll, il] are shown as being mounted on a ball frame Il. troughs are each of a well known construction `having a ilat bottom. and outwardly flared inclined sides l2, I2,.and are shown as being connected togetherin abutting relation with respect tc each other, although they maybe connected together in overlapping relation as well,

A reinforcing `plate I3 is herein lshown as extending across the bottom of and upwardly along opposite sides of one `end of the trough. Ill andas projecting beyond the end thereof. The projectt" therethrough when the troughsare in connected c relation with respect toeach other. it being understood `that a reinforcing plate lil` `extends across one end of` each trough I0 and that a reinforcingplate I4 `extends across the opposite` end of each of said troughs.4

The ball frame II may be of any well known form and is herein shown as including alower frame member l5, suitably held in fixed relation with` respect to the` ground during operation of the conveyonand an` upper frame l mounted thereon and guided. for reciprocable movement therealong on balls I1, I1.

The upper frame I6 of theball frame II is provided with a pair of longitudinally extending upright ears lll, I8 `disposed at opposite sides axes extending transversely of the conveyor on laterally extending pins 2|, 2I mounted adjacent l vte lower ends of said. lugs and extending outwardly therefrom,` A stop 22 extends inwardlif` from the lower end of each supporting lug` `lil adapted to engage a `stop 23, projecting `upwardly from cross frame member `241 of the vupper frame ld. Said stops 22, 22 and 23, 23 serveto limit inward movement 4of said trough supporting lugs` with respect to their associated ears I8, i8 when said troughsupporting lugsare in an upright position. It should here beunderstood that said trough supporting lugs are pivoted` downwardly when inserting said pins through the apertured portions of said ears.

Each trough supporting lug I91has an upper head portion extending angularly downwardly in a plane generally perpendicular to the plane of the lower portion ofthe associated inclined side IZ of the trough` IIl. Said upper head portion has an inner face 25 conforming substantially to the angle of inclination of the inclined side I2 of the trough IU and adapted to be abutted by said inclined side of said trough. Said supporting lug alsohas opposite forwardly and rearwardly facing engaging faces 21, 21, inclined inwardly from the inner face 2li, towards the longitudinal center of said lug. `Said engaging faces are adapted to be engaged lby abutment plates 29, 2B, herein shown as being formed. integrally with and closingadjacent ends of reinforcing members 30, 3D for the sides `of said troughs. Said reinforcing members extend along and are secured to the outsides of said inclined sides of said troughs for a portion of the lengths thereof and taper `from said `abutment `plates inwardly towards the sides `of said troughs. Said abutment plates; `are also .nclined towards eachother `as they extend out- 3 wardly from said troughs, so as to conform to the angles of said engaging faces 2l, 21.

Each trough supporting lug I9 has a longitudinally extending pin 3I mounted in the upper head portion thereof and extending forwardly and rearwardly; from opposite sides v thereof. Said pin is adapted to extend through apertured portions of the abutment plates 29, `29, to form a positive means for supporting said abutment plates and adjacent ends of said troughs on said trough supporting lugs.

A C-clamp 33 is provided to positively hold the abutment plates 29, 29 in engagement with the engaging faces 2l, 2l of the supporting lugs I9, I9. Said C-clamp, as herein shown, has a pair of vertically spaced engaging ends 34, 34 on each side thereof, which are adapted to extend along opposite sides of the pin 3| and engage theouter faces of the abutment plates 29, 29. A tongue 35, having, an 'elongated aperture 39 form-ed therein, extends angularly outwardly; from the supporting lug I9 in the general plane of inclination of lthe head of said supporting lug. Said tongue is adapted to extend through an outer apertured portion of each C-clarnp. i

A'The outer end of each CI-clamp 33 is provided with a slotted portion 36 opening to the outer side thereof, which is adapted to receive a yieldable wedge-shaped keyv 3l. Said yieldable key is,A adapted to lextend through said `aperture Y39 of said tongue and engage the inside of the slotted portion of said C-clamp. Said key may be made from spring steel and is herein shown as being so formed that it will tend to spring outwardly and'will yield inwardly as it is driven through the aperture 39 of the tongue `35 into engagement with the slotted portion of the C-clanip 33. Said key and @clamp will thus draw the abutment plates 29, 29 into engagement with the engaging faces 2l, Z'I when said key is driven through said apertured portion of said tongue, and said key when driven in Iplace will tend to spring outwardly and firmly hold said abutment plates andengaging faces 'in engagementfwithv each other, and will thus form a positive means for rigidly connecting adjacentr ends of thel troughs I9-, ID together. v

The supporting vlugs I9,` I9 are'usually connected to the ears I8, I8 of the ball frame II by cotterkeys so asV not' to be lost when the troughs are disconnected therefrom. When adjacent endsof the troughs I9, I9 are being connected together, the lug I9 on one side ofthe trough line,

is vfirst pivoted to lan upward positionv and one projecting end of the pin 3I is inserted vthrough the apertured portion vof one abutment plate 29. The opposite side of said trough is then mounted on the opposite supporting leg I9 in themanner just described. The adjacent end of the next adjacent'trough is then mounted on the. opposite projecting end of the pin 3I. The C-clamps 33, 33 are then engaged with the outer sides of oppositeabutrnent plates 29, 29 and moved or driven inwardly along said plates until the. key 31 may be inserted through the aperture 39 of the tongue 9 5. Driving of said keys through `said apertures of said tongues Will movesaid C-clamps inwardly a further distance and will positively engage adjacent abutment plateswith the engaging faces 2, 2? of their troughsuppo'rting lugs I9, I9, and said keys tending to expand or spring outwardly will rmly hold said C-clamps,` in posi# tion and hold adjacent ends of the troughs in connected relation withA respect to each other.
